Nissan Motorsports Oil Coolers
 

Hey guys,

I wanted to give you a heads up about another oil cooler option that has recently become available. It's an oil cooler kit created by Nissan Motorsports and can be ordered through any Nissan dealer; the parts advisor might not be aware of the part, but he/she should be able to find it with the part number.

Part Number: 21300-SS370
MSRP: $780

Here is a link to a quick blurb that Edmunds wrote on it with a picture of the components. I don't have any other pics, but I've seen the kit in person and the components are top notch.

Thanks!

So it's basically the Nissan version of the Stillen kit, with a slightly larger core, for $360 more? No thanks, Nissan :)

Big thanks, Steve. So, I can walk into my dealership and have this cooler put in my car? :excited:

Nissan Motorsport parts are not covered by the factory warranty :mad:

I don't know if they will be making an exception in this case or if they will force us to wait for Nismo version (which will probably be identical).

they should be calling US to have us bring in our cars to have these put on!

My understanding is that the oil cooler kit is a Nissan Motorsports Competition Part, which is different than a Genuine Nissan Accessory (comes with a warranty).

The Stillen kit is definitely a nice and less expensive solution, but the core is a lot smaller. In terms of capacity the Nissan Motorsports kit is a lot closer to the Central 20 kit from Japan, which is significantly more expensive.

I don't know what Stillen's targets were, but based on the core size shown in their pictures, it seems unlikely that it would provide enough cooling for a 20 min track session at a HPDE in hot climates (80+ deg F).

Not trying to knock the Stillen kit in any way because it looks like a nice kit at a great price. I'm just glad that there are more more (arguably) affordable solutions than the ones from Japan, which can cost a couple grand!

I guess we'll know soon enough. If the STILLEN unit doesn't keep me cool for 20 minute sessions on the track, then I guess its off to Setrab for a bigger core. It should be very easy to modify the existing kit to accommodate a larger core.

So RCZ, what do you think after your track session this past weekend? Are you going to get a bigger core? I was surprised that the Setrab core in the Stillen kit only has a capacity of .4 qt (I have the kit in my garage and looked up the part no. on Setrab's website). Doesn't seem like much. But apparently the soon to be released Technosquare kit uses the exact same core.

I hit 250 today just driving, no stop-n-go traffic, no hills, just driving. Not that I can afford to spend that kind of money on a part that should have come with the car, but I suppose the options are thin.

Then why would Nissan sell headers and intakes for Z's and G's, if they are not going to cover the warranty?

Ah, finally! I had been looking for someone that could tell me which core comes with the Stillen kit? Is it the 19 row?

Don't forget to account for the lines and extra plumbing.. when all said and done it's an extra quart..

Yep, good point. But it's still .4 qts that's being cooled at any given moment in time, right?

According to this link (Setrab Oil Coolers) yes, this is a 19-row core.

Thanks semtex!

LOL.. yes.. should have some additional info for you guys on your requests for something beefier here shortly..

Oil Cooler
 

After a weekend of spirited driving car went into limp mode fairly quickly, and temps stayed about 260 or so with mild driving, talked with dealership in which they say they will honor the warranty with this cooler as long as they install.

^get that in writing !
when you get it installed. But y do we gotta pay for this.

Will be sure to get in writing, and I agree with everyone we should not have to pay to make a so called performance car perform. Should have part installed next week.

I was under the impression that when a Nissan competiton part fails, the PART itself is not warrantied. I didn't think it affected the warranty of your car unless it could be proven that the part that failed was indeed the cause of the would be warranty repairs.

This might be a dumb question but say someone goes with an aftermarket oil cooler of their choice and something were to happen to the car and needed repair at the dealership, wouldn't it be easier just to take the oil cooler kit back off rather than dealing with having issues of them honoring the warranty? I also feel that Nissan sould have installed an oil cooler on the car from the get go and the one soon to be offered for us from Nissan will be a bit pricey. I save all my stock parts just in case something unexpected happens. It might be extra work but you gotta do what you gotta do right?

I live in central California. The air temps there are already hitting 105F. My oil temps with spirited driving around town where speeds were slow were up to 265F, but easily hitting 250F every day. I got the Stillen (Setrab) oil cooler for $425 and had Bakersfield Nissan install it, charging me 4 hours @ $90/hour. I had them do an oil change with ester oil at the same time and they included that in the 4 hour labor charge.

Now, my oil temps have maxed at 235F. Usually it goes no higher than 220F. Out doing canyon carving, it still stays at 220F, which is lower than romping on it a few times in traffic. Probably because of more air flow across the cooler at road speeds. I'm guessing that track speeds may keep temps lower than in the city too, even though you're working the engine hard.

They used the Setrab unit on all the Nissan press vehicles and they were running them in the desert at 80+ F in track conditions and no one ever mentioned "limp mode" in the initial reviews of the 370z.

It would be an expensive and painful mistake to find out the Setrab unit is deficient for track use by installing it. If anyone with a Setrab unit has had to go to limp mode at the track, please tell us!

Oh well for nissan honoring the warranty once I got to the Dealership the story had changed so off to customer affairs will see if I get a response. Daily outside temp around 90 oil temps 260 to 270

any update about the beefer stillen oil cooler?

All of the specs are mapped out, we just need time with a vehicle, which should happen next week, and we can finalize everything.

19 row vs. 34 row
 

FYI- the 19 row 6 series (6 inch length) Setrab has a 27,000 to 37,000 btu/hr (heat dissipation per hour) rating.

A 34 row 6 series has a 43,000 to 59,000 btu/hr rating.

That's almost double the cooling capability.

We've done some specific analysis of bigger cores, and cooling abilities, and believe we have found a great solution for the guys wanting maximum cooling.

This will also include an upgrade path for those who have the current STILLEN kit.

More information soon..

Sweet! I like the "upgrade path" idea. I haven't been having issues with the current Stillen/Setrab unit, but I'm not tracking my car. It's nice to know that it won't be a problem when I want to.

I will be tracking my Z and I want that level of protection. I used to take my G35 to Summit Point Speedway but have been holding off on the 370Z until I get an oil cooler. The Nissan Motorsports unit looked perfect until I realized it did not have a thermostatic capability. It can get cold in the winter in northern Virginia. From what I hear, the Stillen unit will be equivalent to the nissan motor-sports core and has a thermostatic sandwich plate.

I spoke with my dealer and they recognize Stillen as an approved after-market parts supplier. Do you know how many other companies they mentioned... other than Nismo... none. Of course, the dealer would have to do the install.

I am not saying that the Stillen unit is any better than just purchasing a Setrab cooler, Mocal thermostatic sandwich plate, and Goodrich lines. But at least Nissan recognizes this company. This should be worth the additional cost if you find your self in the unenviable position of fighting a warranty claim.

Stillen. Let me know when that beefed up thermostatic cooler is available. I will be the first one on the list.

Hey, cut me a deal and I'll place Stillen stickers on my Z...:rolleyes:

Oil cooler flow rates
 

I am interested in the oil flow rates using typicall aftermarket oil coolers (Mocal,Seatrab,etc.) Anyone know the oil flow rate for the 370Z?

Also, anyone install a oil pressure gauge on a 370Z yet?

I believe Modshack has oil pressure monitored.

What dealer in Austin Town North? thay's were I got my Z in Jan 09

After asking the dealership to put this in writing they quickly backed down since the Nissan Oil Cooler is considered a nismo competition part and does not come with any type of warranty from Nissan. The dealer will only point towards you warranty manual which is vague on the issue. I also checked around with other dealerships with the same response. Dealers say that by putting on an oil cooler will not affect you warranty unless the oil cooler fails and causes the damage. (Which from a legal standpoint I understand that this is the case) From several talks with consumer affairs, by placing an oil cooler on the vehicle that they classify as a competition part that the car has been modified for competition use therefore having the potential to void your power train warranty however the did say that your radio would still be covered.

Good thing for that!

Anyone have any idea how cool Town North is in terms of being mod friendly? Im curious about when it comes time for service/repairs.

Hey everyone new member and looking into a 370z and doing research. I own a BMW M3 and I have read about this oil overheating issue. BMW 335i and 135i owners had problems with the High pressure fuel pump failing as car goes into limp mode and is a safety issue. They reported it to the NHTSA Home | National Highway Traffic Safety Administration(NHTSA) | U.S. Department of Transportation and filed complaints. Im sure if most of you file complaints here Nissan will have to put a recall out on these cars as there may be a investigation on this topic. Its ashame that a performance car is overheating and Nissan is not helping owners and making them pay for their mistake good luck with this situtaion I hope this helps you guys out.

This is not an issue or a problem or a defect or a... you get the idea. It's totally overblown. For on-the-street operation no one on this forum AFAIK has had their vehicle go into the protective limp mode because of high oil temperature. Some have experienced it while tracking their cars and that is remedied with an oil cooler...which Nissan acknowledges. The sky is NOT falling, thank you very much.:tup:

+1

For all the "forum racers" who will never see a track day... get over it. The overheating problem is limited to those who track their vehicle.

Anyone who tracks their Z (or any other production car) knows that the brake pads, brake lines, LSD fluid, brake fluid, and differential are not up to track usage.

Funny how you don't see thread after thread regarding these issues.

Ok ok good to know.

People who plan to significantly increase the horsepower also are going to have to do this mod.

Good info, OP. I'm ordering a complete Nismo Oil Cooler kit tomorrow.

I went to my dealership yesterday evening and was looking at 370s. I asked the salesman if they sold the cooler and installed them since I'd want it done before I got the car. He had no idea about and said he'd ask his manager in their meeting the next morning (today.)

I just got an email, which isn't too clear, so i'll try to clarify and see if he is or isn't blowing smoke up my ***, but according to him, all of the 2010 370z have the oil cooler installed from the factory.
